And for new users choosing a distro with big user base (thus having a better support system) should be a top priority. Instead newbies are often advised to use an obscure distro that in theory might be a good fit, but isn't. Probably those who do the recommendations are Linux testers (using VZ) rather than Linux users and mostly evaluate a distro based on install process and out of the box usage.

Configuring a big distro to your needs is much better than choosing a nishe distro.
